Abstract

This disclosure describes techniques for improving route advertisements. In one example, generating, by a software-defined networking (SDN) controller that manages a plurality of compute nodes, based on a unique identifier of a virtual network, a route target value for the virtual network, wherein the virtual network comprises virtual network endpoints executing on the compute nodes; and outputting, by the SDN controller and to a routing protocol peer device, a virtual private network (VPN) route that includes the route target value for the virtual network and a virtual network prefix associated with the virtual network, the VPN route for routing to the plurality of compute nodes executing the virtual network endpoints of the virtual network.
